Steam bubbling device and steam power system

Abstract

The invention provides a steam bubbling device and a steam power system. Wherein, the steam bubbling device includes: multi-layer nozzle pipes, the multi-layer nozzle pipes are nested in sequence; the adjacent nested nozzle pipes include an inner pipe and an outer pipe, and the inner pipe has a steam inlet, so The outer pipeline has a steam outlet, and there is an irregular labyrinth channel between the steam inlet and the steam outlet. The side wall of the labyrinth channel has a plurality of anechoic chambers of different sizes. The acoustic chambers communicate with each other through muffler holes. The steam bubbling device provided by the present invention has good noise reduction performance, can eliminate the characteristic spectrum, and reduce the noise of steam injection with large pressure difference. At the same time, the setting of the labyrinth channel can also avoid the phenomenon of condensate backflow under low flow conditions. Avoid low flow "water hammer".

Description

technical field [0001] The invention relates to the technical field of steam power, in particular to a steam bubbling device and a steam power system. Background technique [0002] In order to ensure the overall cycle efficiency of the steam power system of the offshore platform, the condensing pressure is generally low. At the same time, in order to delay the oxidation and corrosion of the equipment, it is generally necessary to deoxidize the condensed water. Limited by the precious space and weight of the offshore platform, the steam power system of the offshore platform can use a thermal oxygen removal device to initially remove the dissolved oxygen in the condensed water and reduce the amount of dissolved oxygen in the condensed water. [0003] Generally, the steam in the thermal deaeration device is new steam or exhaust steam generated during the operation of the power system, and the steam pressure is significantly higher than the condensate pressure, and the vibration...

Problems solved by technology

[0005] The present invention provides a steam bubbling device and a steam power system, which are used to solve the problem that although small hole injection and multi-stage throttling can reduce steam injection noise to a certain extent in the prior art, it is difficult to achieve a satisfactory effect. And the pressure drop is large, and it is still difficult to eliminate the defect that the prominent frequency spectrum of vibration noise is still difficult to eliminate, so as to achieve the goal of eliminating the characteristic spectrum and reducing the noise of steam injection with large pressure difference
